摘要
The transient process inside dual-pulse solid rocket motor during secondary firing was studied by using a system of X-ray real-time radiography (RTR) technique. The blowout pattern and the motion law of the plugs inside the first stage combustion chamber were found out by analyzing the RTR images. By using advanced image processing techniques, the mean flying velocities of the plugs after blowout and the reflection velocities of the plugs after impaction on the convergence section of the nozzle were obtained.
